	# Our patch does two things for us; First, it syncs up with Debian's
	# iproute 20010824-9 package; Secondly, it adds htb3 support.  The Debian
	# patch tweaks the iproute compile so that we use an included pkt_sched.h
	# header rather than looking at the one in /usr/src/linux/include/linux.
	# This allows us to always enable HTB3 without compile problems;
